ipq806x: Add support for IPQ806x chip family

Patches are generated using the "format-patch" command from the
following location:
*https://www.codeaurora.org/cgit/quic/kernel/galak-msm/log/?h=apq_ipq_base
*rev=0771849495b4128cac2faf7d49c85c729fc48b20
Patches numbered 76/77/102/103 have already been integrated in 3.14.12,
so they're not in this list.

All these patches are either integrated are pending integration into
kernel.org, therefore these patches should go away once the kernel
gets upgraded to 3.16.

Support is currently limited to AP148 board but can be extended to other
platforms in the future.

These changes do not cover ethernet connectivity.

+Subject: [PATCH 106/182] clk: qcom: Properly support display clocks on
+ msm8974
+
+The display clocks all source from dedicated phy PLLs within their
+respective multimedia hardware block. Hook up these PLLs to the
+display clocks with the appropriate parent mappings, clock flags,
+and the appropriate clock ops. This should allow the display
+clocks to work once the appropriate phy PLL driver registers their
+PLL clocks.
